Gnathostoma spinigerum is a parasitic nematode that causes gnathostomiasis in humans, also known as its clinical manifestations are creeping eruptionlarva migransYangtze edemaChoko-Fuschu Tua chid and wandering swelling.

Gnathostomiasis in animals can be serious, and even fatal. The first described case of gnathostomiasis was in a young tiger that died in the London Zoo in The larval nematode is acquired by eating raw or undercooked fish and meat. The eggs hatch in fresh water and the larvae are eaten by water fleas of the genus Cyclops. The water fleas are in turn eaten by small fish. Eventually, the larvae end up in the stomachs of carnivoresusually cats and dogs. It then takes another six months http://christianlouboutinuk.co/volksmedizin-zur-behandlung-von-wuermern.php mature.

As humans are not a normal host for the larva, they do not mature in humans, but can Würmer 5 mm various degrees of damage, depending on where the larva wanders in the body. Würmer 5 mm within the genus Gnathostoma are recognized by a bulbous head with a pair of lateral lips surrounding a mouth on the longitudinal axis.

The cephalic region is covered by transverse rows of cuticular spines. Internally, the head is divided into four glandular cervical sacs that attach near the esophagus, as well as four hollow spaces called ballonets, each being continuous with a cervical sac via a central canal.

The body is typically pink and is also covered Würmer 5 mm with circles of flat spines, which become sparser and single-tipped further toward the end. Behind a bare region that constitutes roughly Würmer 5 mm of the body length, many small spines can be found on the posterior tip.

As a nematode, Gnathostoma spinigerum has cylindrical, a cuticle layer with three main outer layers made of collagen and other compounds. The outer layers are non-cellular and are secreted by the epidermis.

The cuticle layer protects the nematodes so they can invade the digestive tracts of animals. Nematodes have longitudinal muscles along the body wall. The muscles are visit web page arranged in bands. Dorsal, ventral and Würmer 5 mm nerve cords are connected to the main body of the muscle.

As a nematode in the group Secernentea, Gnathostoma have specialized Würmer 5 mm excretory system with three canals. The canals are arranged to form an H. Würmer 5 mm are different Namen Drogen Würmer males in that they possess only two large papillae around their slightly rounded posterior ends.

From the side view, the dorsal outline is rounded, whereas the ventral Würmer 5 mm appears flat. Males have eight caudal papillae encompassing the anus on their bluntly rounded ends. Characteristic of males is the presence of blunt spicules that play the important reproductive role of holding open the vagina during sperm transfer. These male copulatory organs measure 1. Just before molting into an Würmer 5 mm, fourth-stage larvae have eight transverse rows of cephalic hooklets.

At this point of development males can easily be differentiated from females based on identifiable sexual organs. The distinctive swollen head morphology, in addition to the four rows of hooklets, already becomes apparent in second-stage larvae.

Eggs have a polar cap at only one end and are laid un- embryonated Würmer 5 mm pitted shells. Although Gnathostoma spinigerum are considered endemic to Thailand, they are also found in many other countries of Southeast Asia.

These nematode parasites have also been reported to be found Würmer 5 mm Japan, Australia, United States, and Mexico. However, the incidence of infection is rarer outside the Asian continent [5]. Gnathostoma spinigerum normally could be found in wet tropical environments. Larvae can infect Würmer 5 mm classes of animals.

In addition to freshwater fishes, domestic duck, Anas platyrhynchus and the domestic chicken Gallus gallus domesticus carry the parasite in Thailand. In a study done in Siam, researchers have proposed a method of prevention of gnathostomiasis. It states that humans can become infected via eating fresh water fish. For example, a popular dish serving fermented fresh water fish is popular among the women of Siam, which may explain their higher incidence of the infection. Laboratory testing on mice treated once or twice daily with albendazole were shown to have a significant reduction in worm count when compared to the untreated mice group.

On the other hand, there Würmer 5 mm other antihelminthic drugs available such as bithionol, thiabendazole, metronidazole, and others, that did not reveal any significant therapeutic effects in experimentally G.
